2 Claims. (Cl. 72-136) This invention relates to construction tools, and particularly to plasterers featheredge.

customarily the featheredge used by plasterers for use in connection with substantial expanses of wall to be plastered comprises a tapered wood board. It has been found that such simple apparatus is difiicult to manipulate and ofttimes subjects the hands of the user to muscular strain.

It is an object of the present invention to provide a new and improved featheredge that has provisions whereby the hand of the user can grasp the tool with comfort.

It is another object of this invention to provide a device of this character which permits a greater degree of control by facilitating manipulation by the user.

It is another object of this invention to provide a device of this character which is simple and inexpensive yet sturdy in construction.

This invention possesses many other advantages, and has other objects which may be made more clearly apparent from a consideration of one embodiment of the invention. For this purpose, there is shown a form in the drawings accompanying and forming part of the present specification. This form will now be described in detail, illustrating the general principles of the invention; but it is to be understood that this detailed descrip tion is not to be taken in a limiting sense, since the scope of this invention is best defined by the appended claims.

Referring to the drawings:

Figure 1 is a pictorial view of a device incorporating the present invention;

Fig. 2 is a transverse sectional view of the apparatus shown in Fig. l; and

Fig. 3 is a diagrammatic view showing a manner in which the device of Fig. 1 may be used.

A featheredge is generally of elongate form and uniform in cross section. It comprises a main body section or plate 11 bounded by longitudinal, parallel and straight edges 12 and 14. One longitudinal edge 12 is intended to contact the wall upon which plastering material is applied.

An angled flange 13, formed integrally with the plate 11, extends longitudinally thereof. One leg or plate 17 of the flange 13 joins the central portion of the plate 11 along a line parallel with edge 12 and is slightly rearwardly inclined. The other leg or plate 16 of the flange 13 is integral with plate 17 along the line of the apex of the angle formed therebetween, and extends in spaced parallel relationship with the plate 11. Said line of the apex of the angle extends parallel with edge 12. The entire structure can conveniently be made as a lightweight aluminum extrusion.

The flange 13 forms, with that portion of the plate 11 adjacent the trailing edge 14, a channel-shaped space 15.

The fingers and adjoining portion of the palm of the hand of the user may be placed along the exterior surface of the flange 13. The terminal portions of the fingers may rest against the inclined wall or plate 17 of the flange 13 that joins the plate 11. The thumb and adjoining portions of the hand may be placed in the space 15 to engage the inner side of the flange 13. If desired, the thumb and adjoining portions of the hand may be placed over plate 11, the fingers being placed substantially as previously described. The flange 13 and plate thus form a convenient grip, and a comfortable position of the hands of the user is ensured.

In Fig. 3, the device 10 is shown in use. The device may be used either in a position at right angles to the wall 18 or slanted upwardly or toward the direction of motion of the featheredge, as desired by the operator. In the lower portion of Fig. 3, the device 10 is shown in cooperation with the lower portion of the wall 18, the wrist 19 of the arm of the user being pivoted slightly inwardly. As the device is moved to an upper position with respect to the Wall 18, the wrist 19 pivots outwardly. No substantial muscular effort is required to be exerted by the digits of the hand.

During use, the featheredge 10 can maintain desired angularity with respect to the wall with only slight eifort and without discomfort.

A great degree of control of the featheredge 10 is permitted for the reason that the flange 13 provides a secure grip for the hands of the user, and for the reason that the hands of the user are thereby positioned close to the operative edge 12.

After continued use, the edge 12 can be restored by a simple machining operation.

If desired, the space 15 may conveniently receive and hold a wood strip in order to provide another type of working edge.

The invention claims:

1. A featheredge comprising an elongated substantially flat plate member having a pair of substantially parallel and substantially straight line opposite longitudinal edges, a second substantially flat plate member disposed in a plane substantially parallel with and spaced from said first mentioned plate member and having a pair of substantially parallel and substantially straight line opposite edges, said members being oriented with all said edges substantially in parallel relationship withone another, a first of said second member edges being oriented over said first member and intermediate said two edges of said first member, and a third plate member having a pair of substantially parallel and substantially straight line opposite edges, a first of said edges of said third member being integral with said first member along a line intermediate said two edges of said first member and uniformly spaced from a first of said edges of said first member, and the second of said edges of said third member being integral with said second member along said first edge of said second member, said second edge of said third member being rearward of said first edge of said third member relative to said first edge of said first member, to provide an inclined portion along said third plate member adapted to be contacted by fingers of a user when the second edge of the second member is grasped by the thumb, whereby said second and third plate members form a hand grip for grasping the featheredge in use.

2. A featheredge as defined in claim. 1, wherein said third plate member is substantially flat.
